AI Technical Summary

Technical Problem

Existing discontinuous reception (DRX) technologies face challenges in accurately representing non-integer periodicities, leading to rounding errors and increased delays due to skipped DRX cycles.

Method used

A mechanism is introduced where a network device transmits a configuration of discontinuous reception to a terminal device, which determines a target start time offset for the DRX cycle using a predefined formula that avoids rounding errors, ensuring accurate alignment with rational number representations.

Benefits of technology

This solution effectively reduces delays and ensures accurate DRX cycle execution by eliminating rounding errors, thereby improving the rational discontinuous reception cycle.

Abstract

The present disclosure relates to a solution on improving rational discontinuous reception (DRX) cycle is proposed. In particular, a network device transmits, to a terminal device, a configuration of a discontinuous reception indicating at least one of a DRX cycle of the discontinuous reception or a start time offset of the DRX cycle. The terminal device determines, based on a predefined formula, a target start time offset for an on duration of the DRX cycle without rounding errors. The target start time offset is ensured to match the start time offset of the DRX cycle when the DRX cycle is represented as a rational number. The terminal device performs the discontinuous reception based on the determined target start time offset. In this way, there are not rounding errors when the DRX cycle is represented as rational number, thereby reducing delays for transmissions.
